Vision Plus contains Omega-3 fatty acids that are a special class of polyunsaturated fatty acids which are commonly found in plant seed oils, nut oils and oily fish such as sardines and salmon. A large number of scientific studies worldwide have highlighted the multiple benefits of dietary Omega-3 fatty acids in areas as diverse as heart, brain, and normal vision. The two most researched Omega-3 fatty acids are Docosahexaenoic Acid (DHA) and Eicosapentaenoic acid (EPA). DHA contributes to the maintenance of normal vision. Omega-3 fatty acids play an important structural and functional role in the retina, the part of the eye that detects light. DHA is a component of photoreceptor cells which are responsible for converting light into nerve signals. Photoreceptors contain the highest concentration of DHA of any cell in the body, with DHA accounting for over 50% of the total fatty acid content. Adequate levels of DHA must be maintained for the retina to continue to function properly and to maintain normal vision. Visionace Plus provides vitamins C and E plus zinc and selenium minerals which contribute to the protection of cells from oxidative stress. Visionace Plus contains high quality natural Lutein Esters.
